We build native Android apps in Kotlin, with Jetpack Compose as the default UI toolkit. Native gives you the full platform: Material 3 done properly, new Android APIs the day they ship, and enough performance headroom to run well on flagships and on the mid-range devices most of the market actually uses.
Android's defining constraint is device diversity: thousands of models, a wide spread of chipsets and memory, and screens from compact phones to foldables and tablets. We treat that as an engineering requirement from day one: adaptive Compose layouts, baseline profiles for fast startup, R8 optimization, and testing on a device matrix built from your users' actual analytics, not from whatever happens to be on the desk. If cross-platform would serve you better, we say so early; we build with React Native and Flutter too, so the advice is not self-serving.
Delivery runs through Google Play the way Google intends: internal and closed testing tracks from the first sprint, pre-launch reports on real devices, an accurate data safety declaration, and a staged rollout that expands from a few percent to full release only while crash and ANR rates hold. We also keep the app compliant after launch, target API level deadlines included, so it does not get delisted a year later.
